Are these compatible and able to be used with Google Home and Google Hub devices? Do they require a RIng Subscription or no?

Hi Chris. Thank you for taking the time to reach out to us with your question. The Ring Alarm Contact Sensor is not compatible with Google Home and Google Hub devices. You can ask your Alexa-enabled device to change the mode to disarmed or armed for your Ring devices, including cameras and Ring Alarm. For more information on integrating your Ring Alarm with an Alexa-enabled device, please visit this link: https://ring.com/support/articles/ms6ai/Connecting-Amazon-Alexa-Enabled-Devices-Ring-Devices. Ring Alarm and all Ring Alarm accessories require a subscription for digital notifications, in-app features, digital arming/disarming, and integration with other Ring, Echo, and third party products.
